Abstract
Preterm babies have a high risk of retinopathy. Doctors conduct fundus fluorescein angiography to determine the state of the blood vessels in their retinas. Disclosed is a system () for conducting fundus fluorescein angiography configured for light weight, small size, and providing a sharp, high contrast angiograph. The disclosed system uses a moulded annular light source, blue and white LEDs () for providing the illumination, an planar annular emission filter () for filtering the blue light, and imaging optics () configured for reducing aberration. The imaging optics () comprises a mechanical iris () to control the amount of light reaching an image sensor (), a tuneable liquid lens () for focusing the image, a green barrier filter () that may be removed from the path of the light—for conducting fundus photography. The white LEDs and the mechanical iris () may be used for conducting fundus photography.
